Upper Mississippi River

Upper Mississippi River

As the mighty Mississippi River winds its way along 230 miles of the western border of Wisconsin, it passes through the heart of the majestic bluff country. Towering bluffs overlook the river's many side channels, marshes, wooded islands and bottomland forests, which provide a home for a wide variety of fish and wildlife.

This complex and busy river faces many competing demands for its resources - the challenge is how to satisfy people's needs without destroying the abundant natural resources that make the Mississippi River so attractive.
